The Grivel Mutant is a helmet made of EPP (Expanded Poly Propylene), with an ABS (Acrylonitrile Butadiene Styrene) reinforcement at the top. ABS is a bit more durable than normal plastic, about 25% lighter, and has four times the impact resistance. This combination of technologies allows a low weight with good all-round protection (on the top and sides) plus ventilation. It features an innovative design with a symmetric hexagon-covered top and a different pattern left to right and has a minimal adjustment system to reduce weight and allow compact storage.
The Mutant comes in two sizes to cover a wide range from 48cm to 62cm.
Materials: EPP, ABS, webbing.
Certifications: CE EN 12492, UIAA 106.
